Abstract:
The reproductive tratheir，physical signs and yield were observed by chosen different roots of the Polygonatum.The results showed that the one-year-old rhizomes which possessed winter buds in the front-end of taproot as the species planted,they had an great superiority on the rate of emergence,height of stem,production and new buds points in such areas over the two groups of rhizomes which only had adventitious buds.Besides，from their physiological index determination,the rhizomes which were one-year-old and possessed winter buds in the front-end had higher content on chlorophyll and soluble protein over those rhizomes which had winter buds in the horizontal axis lateral roots were also abserved.Comprehensive analysis showed that chosen one-year-old rhizomes which possessed winter buds as the seed selection object was an important measure of achieved the goal of high yield and quality and low-cost cultivation in the meantime.
